My number is below sea level.
.
If
you increase my number by 100, it is above sea level.
.
If you decrease my number by 25 it is less than -80.
• My number is divisible by 5.
• My number increased by 5 is -70.

Answers

Answer:

This is an impossible question. This is because it is less than -80 but when you add the 5 it is -70 therefore it must be -75. But it saying it is below -80 therefore this is an impossible question

Which equation represents the following graph?

Answers

The answer is Y=2x+3

A college professor hypothesizes that readers will comprehend more when reading a graphic novel than when reading text with no illustrations. To conduct an experiment, the professor will assign some students to the control group with a reading assignment in paragraph form and other students to the treatment group with a reading assignment in graphic novel form. Afterwards, all the students will take a quiz about the reading to measure comprehension. To assign the groups, the professor will split the students into five groups according to their current grade in the class: A, B, C, D, or F. Within each group, half of the students will be assigned to the treatment group with the graphic novel, and the rest will be assigned to the control group with the paragraph.

The characteristics of the treatment and control groups

should be roughly equivalent because the students are from a randomly chosen class.
might not be roughly equivalent because the students could have vastly different views about graphic novels.
should be roughly equivalent because both groups have a mixture of students with different current grades.
might not be roughly equivalent because the students were not labeled and randomly chosen for each group.

Answers

Answer:

should be roughly equivalent because both groups have a mixture of students with different current grades.

Step-by-step explanation:

The characteristics of the treatment and control groups should be roughly equivalent because both groups have a mixture of students with different current grades.

What is control groups?

It is comprise of the participants where it does not collect the experimental treatment. At the time when the experiment is conducted, the people should be allocated to the group. Also, it should resemble the participants.

Hence, The characteristics of the treatment and control groups should be roughly equivalent because both groups have a mixture of students with different current grades.

Answers

Answer:

Transversal

Parallel Lines

Vertical Angles

Step-by-step explanation:To help you remember: the angle pairs are on Alternate sides of the Transversal, and they are on the Exterior of the two crossed lines.

Parallel Lines

When the two lines being crossed are Parallel Lines the Alternate Exterior Angles are equal. When two lines are crossed by another line (called the Transversal): Alternate Exterior Angles are a pair of angles on the outer side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Exterior Angles: a and h.

What is a logarithm?

Exponentiation's inverse function is the logarithm. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.

The logarithm counts the number of times the same factor appears in repeated multiplication in the simplest case.

The given expression is;

logx = -2

x=log⁻¹(-2)

x=0.01

The value of x will be 0.01. Option C is correct. Antifog is used to solve the problem.

Hence,option C is correct.

Annabelle invested $70,000 in an account paying an interest rate of 6.1%
compounded continuously. Assuming no deposits or withdrawals are made, how
much money, to the nearest ten dollars, would be in the account after 9 years?

Answers

Answer:

121210

Step-by-step explanation:

After 9 years, Annabelle will have $119271.4 in her bank account as per compound interest

What is compound interest?

"Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest."

Given, the invested amount is (P) = $70000

The interest rate is (r) = 6.1% = 0.061

Duration of the investment (n) = 9 years

Therefore, the amount of money after 9 years will be

= P(1 +r )ⁿ

= $70000(1+0.061)⁹

= $119271.4

Therefore, the total amount after 9 years will be $119271.4.

Step-by-step explanation:

a nonagon is a nine-sided polygon, if a regular nonagon was rotated about its center point, which of the following angels of rotation would not map the figure onto itself

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]Shape: Nonagon[/tex]

Required

Angles of rotation that would not map the shape on itself

Side of a nonagon is:

[tex]Sides = 9[/tex]

and a complete rotation is:

[tex]Complete\ Rotation = 360\°[/tex]

To start with, we calculate a possible angle of each rotation:

This is calculated by dividing the complete rotation by number of sides

[tex]Each\ Rotation = \frac{360}{9}[/tex]

[tex]Each\ Rotation = 40[/tex]

The question lacks option; so, it's difficult to give a specific answer.

However, I'll give a generalized answer

For the nonagon to map on itself, the angle must be a multiple of the calculated angle of rotation (40)

i.e.

[tex]Possible\ Angles = 40,80,120,160,200,240,280,320,360......[/tex]

Any angle different from the above listed angles (or any other multiple of 40 not listed above) answers the question.

The angles of rotation that would not map the figure onto itself will not be the multiple of 40 and this can be determined by evaluating the possible angle of each rotation.

Given :

A nonagon is a nine-sided polygon.A regular nonagon was rotated about its center point.

To determine angels of rotation that would not map the figure onto itself, first, evaluate the possible angle of each rotation.

To determine the possible angle of each rotation the following calculation can be used:

The possible angle of each rotation is the ratio of the complete rotation to the number of sides.

[tex]\rm Each \;Rotation = \dfrac{360^\circ}{9}[/tex]

Step-by-step explanation:

A paired T- test is also sometimes called the dependent sample t-test. It may be defined as a statistical procedure that is mainly used to determine if the mean variance between the two samples or units of the observations are zero or not.

It helps to compare the two means which are taken from the same objects, related units or from same in individual.

According to the question, the answer is true as the paired T-test can be reduced to the single mean T- test.
